Used by countless popular YouTubers, Patreon is a site that allows viewers to donate monthly to their favorite YouTubers, and in turn, allows the YouTuber to (if so desired) give rewards back to the viewers. And, despite the site taking about 10% of the donations for themselves, most YouTubers make more money through Patreon than their own channel, according to Bustle.
ChuChu has changed over time—it has slowed the pacing of its videos, focused on the key elements of scenes, and made more explicitly educational videos. But in the wilds of YouTube, the videos with the most views, not the most educational value, are the ones that rise to the top. ChuChu’s newer videos, which have more of the features Johnson looks for, have not had the time to hoover up as much attention, so the old ones keep appearing in YouTube searches and suggestions.

YouTube earns advertising revenue from Google AdSense, a program which targets ads according to site content and audience. The vast majority of its videos are free to view, but there are exceptions, including subscription-based premium channels, film rentals, as well as YouTube Premium, a subscription service offering ad-free access to the website and access to exclusive content made in partnership with existing users.
